Observation of the Charge Resonance Band of Hemibonded (H <sub>2</sub> O) <sub>2</sub> <sup>+</sup> in the Gas Phase
High Resolution Image Download MS PowerPoint Slide Electronic spectroscopy of (H 2 O) n + ( n = 2 and 3) radical cluster cations was investigated in the ultraviolet–visible region. For (H 2 O) 2 +, the charge resonance band attributable to the hemibonded isomer, an elusive species previously observed spectroscopically only in helium droplets, was identified in the gas phase. This observation establishes electronic spectroscopy as a sensitive probe of hemibonded structures in water radical cations.
